A Crypto-Mystery: Is $140 Million Stuck or Missing?

Gerald Cotten launched Quadriga in December 2013. The exchange claimed to be one of the largest in Canada, allowing customers to trade a handful of cryptocurrencies, including bitcoin and ether.

On Jan. 15, the company announced on its website that Mr. Cotten had died on Dec. 9 from complications related to Crohn’s disease while building an orphanage in India. He was 30 years old. Two weeks later, the exchange filed for bankruptcy protection in a Nova Scotia court.

.. While those suspicious of Quadriga acknowledge the public transactions don’t provide certainty, some say there is a way to determine if the exchange’s money is indeed trapped. A crypto developer named Amaury Sechet suggested Quadriga should publish the addresses of the cold wallets. This would allow anyone to see how much cryptocurrency is in them, even if they couldn’t access it.

Poloniex said it identified accounts that could be related to Quadriga, and is working with appropriate authorities. Bitfinex did not immediately reply to a request for comment. ShapeShift declined to comment.

“Over time trust will build as the coins remains (sic) untouched,” he wrote on Twitter. “If they cannot do this, their story is not credible.”
